truncated cone shape.

In making-receptacles of truncated cone shape of this character a permanent closure in the form of a flanged disk is secured in the lar er end of the receptacle andto close seal the receptacle the open or smaller end iscollapsed by squeezing or pinching the i opposite wall portions together and securing said end in its collapsed condition by amemas leaka e thereof.

bar, usually of pliable metal, of inverted V-shape engaged over the collapsed end and pressing opposite portions of said member together with the collapsed end .of the re ceptacle interposed and secured in such position by upset'portions of the material of said sealing member. The function of the securing member is also to seal the receptacle by retaining thecollapsed end of the receptacle in collapsed condition. However, due to inequalities in the top edge develo d in the making of the receptacle it was ound that said securing and sealing member did not Pgoperly seat upon the closed end of the receptacle with the result that the contents of the receptacle would be partially opened to the atmosphere and a consequent'deterioration of the contents of the receptacle as well It is t e object of the present'invention to overcome the above disadvantages by so constructing and arranging the blank from which thereceptacle body is formed so that when the open end of the rece tacle is collapsed the edges of the collapse sides at said end of the receptacle will at all times be in a uniform plane substantially parallel with the base or bottom of the receptacle whereby the securing and sealing member may be properl seated thereon and retain the collapsed wa s in contiguous and tight relation.

In the drawing accompanying and forming a part of this specification, Figure 1 is a plan' view of my improved died-out blank.

Similar characters of reference designate like parts throughout the difi'erent views of the drawing.

In carrylng out the invention a suitable die is providedto cutout from a sheet or web a blank substantially of quadrilateral form, as shown in Figure 1, having an end, to constitute the base of the receptacle or container, of arcuate or curved form, as at 8, the same being in the arc of a circle whose center lies in a ine extending vertically to said end and substantially centrally between the termini of said end, as represented at 9.

The opposite sides 10, 11, converge from the to the top end of the sheet the inclination of said si es being at the same angle. The edge of the blank opposite to the arcuate shaped end is a chord of an angle intercepted by the sides of the angle formed by the edges 10, 11, which angle has its vertex at the center from which the arc of the base 8 is struck,

said end having three straight line portions,

opposite sides 10, 11 are overlapped, as illusan intermediate portion 14 and opposite end portions 12 inclined at an acute angle to the rhorizontal, as indicated by the dash line 13, and at an obtuse angle to and merging with the intermediate portion 14, as at a and b. The portions 12 and 14 are arranged and dimensioned so that when the upper open end of the receptacle formed from the blank is collapsed, said portions, constituting the upper edge of the receptacle, will be in an even plane, that is, extend in a straight line, and in the form of the receptacle body with the opposite edges 10, 11 in'abutting relation the intermediate portion 14 is of an extent at least equal to both inclined portions 12, and

- said portion 14 is of a l'engtli less than the combined length of both the inclined portions 12 when the marginal portions of the trated, in securin the blank to form the receptacle body. 0 form the receptacle or container the sheet is wrapped or rolled about a horn or'mandrel with the side edges in contiguous relation, preferably overlapped, "so that the one side ed e-portion, such as the side 11, will overlap t e side edge portion to an extent represented by the dash line in Fi re 4. I By t e sheet so formed a receptacle dy of truncated cone'sha'pe is pros duced, as shown in Figures 2 and 3, thesheet being retained in rolled condition by a securing member, such as an adhesive strip 15 en gaied over the edges 10, 11. v

closure is secured in the larger end to constitute the bottom, which closure consists of a flanged disk 16 (Figure 6) inserted into the end with the flange extending outward with the outer edge in parallel relation to the edge of the receptacle and secured therein by rolling the end portion of the receptacle and flan of the closure disk inwardly, as shown at 1%; To facilitate this rolling of the sheet and disk'flange together the corner of the sheet at the juncture of the base 8 with the side 11 is cut away on-an angular line, as at 18, this cutaway portion commencing approximately at a height equal to the length of the flange of the closure disk 16 and extending laterally of the edge 11 to an extent substantially equal to the lap of said edge portion in relation to the edge portion 10.

From asheet of the form as described a receptacle body is produced in which the bottom or base is in a substantially horizontal, lane while the upper edge when viewed rom one side, as in Figure 2, will incline downwardly from oppos te sides and merge substamtially centrally of the receptacle, as

at 19. When viewing the receptacle from the 7 side in another position, as from the left of Figure 2, ,the top edge will incline upwardly from opposite sides and merge substantiall centrally of the receptacle, as at 20. In e feet, as shown in Figure 4, the opposite ed e portions will incline upwardly from the points a, b representative of where the inclined portions 12 of the top of thesheet merge with the intermediate portion 14, and merge substantially centrally of the receptacle. a v

To close ,the receptacle so formed, as shown in Figures 2, 3'and 6, the upper and open end is collapsed; that is, the opposite wall portions are squeezed or pinched together, the wall portion with the overlapped edge and the opposite wall portion being moved relative to each other, as shown in dotted lines in Figures 2'and 3, and as viewed in Figure 2 the central portion 19 of the upper edge will be moved upward longitudinally of the receptacle while the opposite side portions will move downwardly, thus causing the meeting edges of the opposite wall portions to extend in a substantially uniform plane and parallel with the bottom or) base of the receptacle, and in such condition a sealing member 21 (Figure?) of pliable sheet metal is engaged over the top andwill seat against the top edges, and as the opposite portions of said member are pinched together press the opposite wall ortions of the receptacle firmly to ether, tie sealing member being "retaine in position upon the receptacle by up-' setting portions of the metal of said member, as at 22, and forcing said upset portions through the material of the receptacle and into perforations 23 in the opposite portion of the sealing member.

When the open end of the receptacle is 001 lapsed as'viewed in Fi ure 3 the central portion will be moved slig tly downward lo'ngitudinally of the receptacle while the, lateral portions are moved upward and the upper ortion of the receptacle spread, as shown 1n dotted lines in saidfigure, thereby positioning the upper edge of the receptacle in a substantially uniform plane. Receptacles of this character are used as milk containers to which the milk is supplied by filling machines and from which machines they are transferred to a conveyor to be presented vto means to mlla se the open endsand a-ppl the sealing mem er 21 thereto.-*To proper y position the receptacle upon the c'onveyer so that they will be presented in correct position to the seal applying means the sheet is arranged with an indexin the form of a vertical line 24 positioned in predetermined relation to the side-10 of the sheet so that when the receptacle is" formed from said sheet saidindex will be substantially axially of the receptacle, as shown in Figure 2. The sheet, furthermore, is arranged with a horizontal line 26 adjacent the top,'which line is arranged just below the edge of the there is arranged adjacent said line the phrase Cut on this line to indicate that in order, to remove the contents of the receptacle the top portion of the receptacle should be severed or cut on the line 26. The sheet is also arranged with an index line 27 extending downward at an angle to and from the line 26 with the words Fold here rinted adjacent to said line, which is to indicate that the receptacle is to be folded on said line to close the receptacle after the receptacle has been opened by removing the sealin member and a portion of the contents onfy has been used.

Having thus described my invention I claim:

1. As an article of manufacture, a recep tacle blank of quadrilateral form having one end of arcuate sha e the center of the curve of which lies in a inc extending vertical to said end, with the opposite sides of the blank converging from said arcuate shaped end, and the opposite end of the blank having an intermediate portion and opposite end portions extending outward from and at an obtuse the base en toward the top end in a direcangle to said intermediate. portion and terminating at the sides, said intermediate portion being equal to one side of the receptacle at the u per end.

2. s an article of manufacture, a blank for makin a rece tacle body of truncated cone form aving t e opening, thereto at the smaller end and adapted to e colla sad to close the rece tacle, comprising a led-out sheet havin t e opposite sides inclined from tion toward each other and at the same angle with thebase end in an arc of a circle whose center lies in a line extending vertically to the base and centrally between the sides of the sheet, and the top extending inward and downward from the sides and merging in an intermediate portion, said intermediate rtion beingequal in length to one side 0 the receptacle at the upper end vwhen colla 'sed.

3. As an article of manufacture,-a b ank of quadrilateral form for making a receptacle body the opposite sides of which converge from the end constituting the base of the receptacle, the base being arranged in an arc of a circle and the end opposite the base end being a chord of the ang 0 formed and interce ted by the sides and having the opposite end portions inclined from the sides at an obtuse angle to and merg'in with anintermediate rtion, the interme ate portion being of a ength-to form one so ent of the top edge of the body and the inclined portions being of lengths to formthe remaining segment of such topedge.
